Ive been hunting for over a decade with the same gun, a 870 Super mag special purpose, Mark Bansner Truglo choke that throws great patterns, but... ive decided to use it as my backup in lieu of my new Knight TK 2000! I had magnetic sights on the gun, and managed to lose the front sight during a hunt last spring so im done with them! Looking at either the Vital Gear Tommy Max or the Dead Ringer Beard Buster!!! Any advice?
